Abstract

(57) [Summary] [Purpose] To provide a cooking pot that has excellent thermal conductivity and can heat the entire pot quickly and uniformly. [Structure] The thickness of the pot bottom 1a is the same as or thicker than the side wall 1b, and a large number of heat transfer ribs 4 are formed radially on the outer surface of the side wall 1b to transmit heat from the pot bottom 1a to the side wall 1b. . The cross-sectional area of the side wall 1b is expanded at the portion where the ribs 4 are formed, and heat conductivity is improved, so the heat of the pot bottom 1a is immediately transmitted to the entire side wall 1b via the ribs 4, and the entire pot is heated almost uniformly.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a cooking pot used for boiling food.

0002

[Conventional technology]

In recent years, electromagnetic induction heating has been used as a heater for cooking food in a pot. An electromagnetic heater that generates heat from the pot itself, or a halogen heater that uses a halogen heater as the heat source. Heaters, etc. are less prone to fire, air pollution, and heat loss than conventional heaters that use gas. It is rapidly becoming popular as a heater that is safe, clean, and has excellent thermal efficiency. There is one.

0003 However, when cooking food by placing a pot on these heaters, the heater The magnetic field lines emitted by the halogen heater and the heat from the halogen heater act only on the bottom of the pot. The problem is that only the parts are heated locally, and the heat is difficult to transfer to the side walls. It was difficult to heat the entire pot evenly. For this reason, something like this It would be desirable to have a pot that can heat the whole thing quickly and uniformly even when used as a heater. It is.

0004

[Problem that the idea aims to solve]

The challenge of this invention is to have excellent thermal conductivity and be able to heat the entire area quickly and uniformly. The purpose of the present invention is to provide a heating cooking pot.

[0005]

[Means to solve the problem]

In order to solve the above problem, the heating cooking pot of this invention has the same thickness of the bottom of the pot as the side wall. or thicker, and the outer surface of the side wall has a number of heat conductors that conduct heat from the bottom of the pan to the side wall. It is characterized by having ribs for use in a radial pattern.

[0006]

[Effect] By forming ribs on the side wall, the cross-sectional area of the side wall expands in that area, improving heat transfer. When the bottom of the pot is heated by the heater, the heat is immediately transferred through the ribs. The heat is transmitted to the entire side wall, and the entire pot is heated almost evenly.

【Example】

Hereinafter, embodiments of the present invention will be described in detail based on the drawings. As an embodiment of the present invention, a pot for use in electromagnetic induction heating is shown. It consists of a body 1 and a handle 2 attached to one side of the pot body 1.

[0008] The pot body 1 is made of aluminum, and electromagnetic induction is generated on the outer surface of the pot bottom 1a. It is equipped with a magnetic layer 3 as a heating body, and is heated by the heat generated by the magnetic layer 3. The thickness of the pot bottom 1a is the same as or thicker than that of the side wall 1b, and the outer surface of the side wall 1b is A large number of heat transfer ribs 4 are formed radially. Thus, on the thin side wall 1b By forming the rib 4, the cross-sectional area of the side wall 1b is expanded at that portion, and the heat conductivity is improved. In order to improve the temperature, the heat from the bottom 1a of the pot is quickly and evenly transmitted to the entire side wall 1b. Become.

[0009] The magnetic layer 3 is made of a magnetic material such as iron at a high temperature of 1500°C or higher (for example, 1000°C). It is formed by melting it at a temperature of around 0°C and injecting it under high pressure. this magnetic material The thickness of layer 3 is preferably about 0.5 mm. On the outer circumference of the bottom of the pot body 1, the pot bottom 1a is placed above the electromagnetic heater with a certain space. Legs can be formed as necessary for placing the device in a state in which it is placed.

0010 When the pot having the above configuration is placed on the electromagnetic heater 5 and the electromagnetic coil is energized, Lines of magnetic force from the electromagnetic coil act on the magnetic layer 3, and the magnetic layer 3 is stimulated by electromagnetic induction. Since the layer 3 generates heat, the pot bottom 1a is heated first. The heat from the bottom 1a of the pot gradually spreads to the side wall. 1b, but the cross-sectional area of the portion of the side wall 1b where the ribs 4 are formed increases, and the transmission increases. Since the heat property is high, the heat is mainly transmitted through the part where the rib 4 is formed. The heat is transmitted to the entire side wall 1b, and the entire pot is heated almost uniformly.

[0011] The above pot can also be used as is in halogen heaters, gas heaters, etc. The heat conduction in this case is the same as in the above case, but the pot is used in a gas heater. In this case, the heat transfer area for absorbing heat from the flame is expanded by the rib 4, so This, combined with improved thermal conductivity due to the enlarged cross-sectional area, results in very good heating efficiency. Ru.

0012 In addition, since the pot of the above example is configured as a pot for electromagnetic induction heating, The bottom 1a of the pot made of aluminum is equipped with a magnetic layer 3, but the entire pot is made of iron. Alternatively, if not used for electromagnetic induction heating, the whole can be made entirely of aluminum. It can also be formed by

[0013]

[Effect of the idea]

As detailed above, according to the pot of the present invention, a large number of ribs are formed radially on the side wall. As a result, the cross-sectional area of the side wall increases in that area, increasing heat transfer. Heat from the bottom of the pot is immediately conducted to the entire side wall via the ribs, heating the entire pot quickly and evenly. be done. Moreover, compared to making the entire side wall as thick as the bottom of the pot, the pot is lighter. It can be done.
